How to highlight text in audio files?

Question

iPhone

The task is the following, there are audio files and texts for them, it is necessary to make sure that during the playback of audio files, the fragments that were voiced are highlighted in the text. (A kind of subtitles for audio files.) I'm interested in a tool that can do this, preferably a universal one, so that later it can be used on any platform.

Answer 1

Dig towards Karaoke players/makers. Once upon a time I saw a similar program, although it seemed to work with mid and kar files.
